Epidural steroid injection is a treatment for low back pain which allows smaller doses with less risk of side effects and longer duration of relief than systemic administration. From 1 June 1992 to 31 January, 1994, 1 mg/kg of triamcinolone diacetate in 8 ml of lidocaine 1% was administered 56 times to 33 patients who complained of low back pain. Results of epidural steroid injection provided effectiveness in treating various low back pain diseases except postlaminectomy syndrome. However there are no gains about repeated epidural steroid injection.

Flurbiprofen, one of potent nonsteroidal antiinflammatory drugs, has several systemic side effects due to dose dumping effect following oral administration of its conventional solid dosage forms. To reduce these side effects and to sustain therapeutic concentration of the drug, matrix tablets of flurbiprofen were prepared and evaluated for sustained release from the tablets. The matrix tablets of flurbiprofen were prepared with Eudragit, Pluronic, (anhydrous) lactose and colloidal silicon dioxide employing two different preparation methods, wet granulation and direct compression. The dissolution rates of the tablets were evaluated using KP 2 method. Formulation factors that affected dissolution rates of flurbiprofen were the type and content of Eudragit, the type and content of Pluronic, and the tablet preparation method. Several formulations of the matrix tablets showed dissolution patterns close to the simulated profile using pharmacokinetic parameters of flurbiprofen.

Kimura's disease is a chronic inflammatory disease which often presents as a tumor like swelling in the head and neck region. This lesion is benign but it may easily be mistaken for a malignant tumor. Kimura's disease has been confused with angiolymphoid hyperplasia with eosinophilia(ALHE). The cause is unknown, but theories include autoimmune, allergic, neoplastic, and infectious cause by insect bites and parasites. The treatment of choice is surgical removal. Recently we experienced a case of Kimura's disease occuring in the both side of posterior neck triangle area of a 37 year old male patient who was treated with surgical excision and systemic corticosteroid administration.

Radiation recall is an uncommon phenomenon in which administration of a chemotherapy or another systemic agent induces an acute inflammatory reaction in previously irradiated tissues, often weeks to years after completion of radiotherapy. Gemcitabine can induce an inflammatory reaction within an area of prior radiation. Radiation recall is known to medical oncologists, however only few cases have been reported in Korean journals, therefore physiatrist who diagnose and treat the treatment-related physical impairments of cancer patients must know about it. We emphasize the importance of knowledge of this phenomenon when considering the differential diagnosis of painful limb edema in a patient who has received cancer treatment.

Of the different phases of bipolar disorder, bipolar depression is more prevailing and is more difficult to treat. However, there is a deficit in systemic research on the pharmacological treatment of acute bipolar depression. Therefore, consensuses on the pharmacological treatment strategies of acute bipolar depression has yet to be made. Currently, there are only three drugs approved by the Food and Drug Administration for acute bipolar depression : quetiapine, olanzapine-fluoxetine complex, and lurasidone. In clinical practice, other drugs such as mood stabilizers (lamotrigine, lithium, valproate) and/or the other atypical antipsychotics (aripiprazole, risperidone, ziprasidone) are frequently prescribed. There remains controversy on the use of antidepressants in bipolar depression. Here, we summarized the evidence of current pharmacological treatment options and reviewed treatment guidelines of acute bipolar depression from recently published studies.

Injuries and infectious diseases have been the most important public health problems since the beginning of human life. Injuries result in death of about 30,000 people each year in South Korea. In terms of years of life lost, injuries are considerably more costly than either heart disease or cancer. In terms of cost - both the direct costs of care and the indirect costs to individuals, families, and societies of a diminished life-injuries are among the most expensive of all social problems. The main purposes of this study are (1) to describe the outcomes as well as treatment process of brain injured patients and (2) to identify the factors impacting on length of stay during hospitalization and hospital fees. The research method used in this study was to review the medical records of five hundreds brain injured cases using systemic random sampling. The multiple logistic regression was administered to identify the factors impacting on the outcomes. The results are as follow : (1) the consultation .ate was found to be 72.9% while referral rate was 11.2%; (2) nearly 30% of the respondents were hospitalized over 30 days; (3) multiple logistic regression analyses revealed that the determinants influencing LOS were number of consultations, number of lab tests, and surgery; (4) the determinants of hospital fee were severity of brain injury, gender of patients, number of consultations, number of lab tests, and surgery.

Vitamin E, which has its advocates in the treatment of diabetes mellitus. autoimmune disease, cancer and peripheral vascular and thromboembolic disease, has now been alleged to have a powerful antioxident effect and to affect various biological activities such as fertility factor, inhibition of human platelet aggregation and stabilization of biological membranes. The present study was designed to test whether vitamin I(alpha-tocopherol) can : (1) enhance the hemagglutinin response to sheep red blood cells (SRBC), (2) modulate Arthus and delayed type hypersensitivity(DTH) to SRBC and contact hypersensitivity to dinitrofluorobenzene (DNFB). (3) enhance the mitogenic response of murine splenocyte, (4) decrease the recovery of Cryptococcus neoformans from brain, lung, liver, spleen and kidney of infected mice and (5) have an inhibitory or enhancing effect on the induction of active systemic anaphylaxis(ASA) induced by chicken-gamma globulin (CGG) in mice. Mice were given either intramuscular injections of 0.3ml (300mg) of vitamin I before immunization or were infection for 10 consecutive days or were given by vitamin I esophageal intubation, 0.1ml(100mg), for 20 days before sacrifice for the mitogenic response experiments. It was found that vitamin E treated mice showed a significant enhancement in hemagglutinin response, Arthus reaction and DTH to SRBC and contact hypersensitivity to DNFB. There was no significant difference in the mitogenic response to phytohemagglutinin(PHA), but the response to concanavalin A(ConA) or pokeweed mitogem(PWM) was increased in vitamin E-treated mice. Interestingly, the vitamin E administration before C. neoformans infection decreased significantly the recovery of C. neoformans from brain lung, liver, spleen and kidney of the infected mice as compared with that of the control mice, strongly suggesting that vitamin E pretreatment may increase the resistance of mice to the fungal infection. Unexpectedly, vitamin E administration enhanced the production of CGG -induced ASA. Taken together, it can be concluded that vitamin I administration may in-crease the humoral and cellular immune response and resistance. to C. neoformans infection, but enhance the induction of ASA to CGG. Further studies are necessary to clarify the underlying mechanism accounting for these effects.

The purpose of this study was to evaluate the effects of administration of Zea Mays L. on the healing process after periodontal surgery as adjuntives. Authors used 3 kinds of different clinical criteria, depth of periodontal pocket by using the Goldman Fox periodontal probe, degree, of tooth mobility by Periotest, and amount of occlusal force with electronic device. In this comparative clinical study, 30 patients who were divided into two group, 15 ZML administrated group and 15 placebo adminstrated group, were participated. All the examined teeth were isolated with gauze and air spray, and measured each clinical critera on the day of before surgery, 1, 2, 4, 8 weeks after surgery. The results were as follows. 1. The changes of the periodontal pocket depth, on the both of Zea Mays L. administrated group and placebo adminstrated group, revealed the decreasing tendency, and it was shown the time dependent tendency. But there was no statistically significant differences between the two group. 2. In the case of tooth mobility, both group showed the highest severe mobility on the 1 week after surgery. It was observed that experimental group had more effects on decreasing the mobility. But there was no statistically significant differences between the two group. 3. In the case of experimental group, the recovery trend of occlusal forces after periodontal surgery on the molar teeth revealed higher than the control group. But there was no statistically significant differences between the two group. In conclusion, Zea Mays L. may play a favorable role in the healing process after periodontal surgery. It was suggested that further study to evaluate the effects of selective administration on the patient who have systemic diseases should be needed.

The purpose of this study was to evaluate clinically and histopathologically the effects to the periodontal tissue in rats after Cyclosporin A (CsA) administration and to determine whether there is a relationship between dosage of CsA or blood CsA level and the seventy of gingival overgrowth in rats. Twenty 6-week-old Sprauge-Dawley Fats were randomized into 4groups. The control group received olive oil only and the test group received daily CsA in olive oil via gastric feeding for 6weeks at a 3,10, and 30mg/kg. Rats were weighed to evaluate the systemic effect of drug and stone models were made from alginate impressions of upper and lover anterior region at 2 week interval. On completion of offal CsA administration, blood were collected and blood CsA levels were quantitated by TDxFLx analyzer. Rats were sacrificed an6 their upper and lower jaws were removed together with the surrounding gingiva and soft tissue for light microscopic examination. The results were as follows : 1. The weight gain of GsA-treated rats was much less than of the control group and central incisors were gradually displaced and separated in the test groups. 2. The extensive fibrovascular proliferation and scattered inflammatoy infiltrates in an edematous stroma were observed in enlarged gingiva of CsA-treated rats. 3. The increase in buccolingual, mesiodistal dimension of the anterior teeth and vertical height of the interdental papilla showed dose-dependent manner in CsA-treated rats. 4. Significant positive correlation exists between blood CsA level and the severity of gingival overgrowth in anterior teeth. This result indicates that the severity of gingival enlargement in CsA treated rats is correlated with dosage of CsA administration and blood CsA level.
